WINDOW-SASH.

Application filed September 27, 1913.

To all whom it may concern:

Be it known that I, MICHEL REY, a citizen of the French Republic,residing at 52 Rue de Passy, Paris, in the Republic of France, haveinvented certain new and useful Im provements Relating to \VindowSashes, Particularly for Railway- Carriages and other Vehicles, of whichthe following is a specification.

This invention relates to window sashes particularly for railwaycarriages and other vehicles.

The window sashes of vehicles are usually so arranged as to open underthe influence of gravity and to remain closed by resting upon a ledge inthe frame or door in which they slide, intermediate positions beingmaintained by means of a strap or the like which is attached at one endto the base of the window sash and engages at diflerent points in itslength with a knob or button on the frame or door. Such window sashes,when in their raised or partly raised position, are liable to shake somuch, during the travel of the vehicle, as to produce an objectionablerattling noise or even cause fracture of the glass; moreover whenreleased for lowering purposes they fall abruptly unless checked, andare therefore liable to cause the glass to be broken; also, if bycareless handling a traveler raises the window sash to ts full heighttoo suddenly, the shock mag ause the glass to crack.

The means for clamping the window sash when adjusted to any desiredheight are preferably of the kind consisting of members adapted to movein planes perpendicular to the face of the window sash, these membersbeing pivoted atone end inthe known manner but rocked about their pivotsby two bars transversely movable inwardly and outwardly across the frameor door near the bottom of the window opening. The rocking movement ofthe members, due to their cooperation with the transversely movablebars, is preferably brought about by a special formation of the outer orengaging ends of these bars, the latter being for this purpose bent orotherwise formed with a cam-like surface for engagement with the Theunw'pivoted ends of the said members, which may be in the form of rods,are preferably )forked to accommodate the outer ends of theSpecification of Letters Patent.

section on the line 2-2 of Fig. l, and Fig. 3

a horizontal section on the line 33 of Fig. 1, showing a railwaycarriage door in which one embodiment of the improved window sash isincorporated. In Fig. 2 the center cross rail of the door is shownremoved a short distance from the remainder of the door, for the sake ofclearness of illustration. Figs. 4 and 5 illustrate apart from thewindow sash and on an enlarged scale the system of pulleys, the spring,and the stranded wire usedin the window shown in Fig. l, for keeping itnormally closed. Fig. 6 is a sectional plan of the clamping means andoperating handle drawn to a larger scale, and Figs. 7 and 8 are twoelevations, illustrating the means for rocking the clamping rods bymeans of' which the window sash is retained at any desired height in itsframe. Fig. 9 is a plan of the handle and cooperat ing parts foractuating the reciprocatory bars shown in Figs. 6 to 8.

A is the lower part or panel of the door, B B are the vertical membersor posts forming part of the window frame, and C is the cross piece orhead. The lower part A of the door is made hollow as usual, toaccommodate the window sash when lowered, and the posts B B are groovedor rabbeted to allow the window sash to slide therein. In theconstruction illustrated, the window sash consists of a sheet of plateglass D furnished with a button D for manipulating it, and withprotective metal strips D D on its vertical edges. At the rear of eachof the vertical grooves in the posts B B is situated a metal casing E(Figs. 4 and 5) which contains a coil spring E and two Y 7 ingvertically in the casing E and is'nor-- mally thrust to the foot of thesame by the spring E. V

One end of a stranded wire F, which is passed around the four pulleys EE E and E*,'is secured to the casing E, at apoint just below the framein'which the pulleys E E are .mounted'and the other end is secured tothe window sash at a convenient point, for example by being bound aroundthe pin D by which the metal strip D is secured to the glass D. Thestrength of the spring E is such that it normally keeps thewindow sashin its closed position. When therefore the window sash is released fromits open or an only partly closed position, it automatically closes toits full extent; a pad of rubber or the like C (Fig. 2) is placed in thegroove of the cross piece or head G to prevent the glass from receivinga shock on arriving at its fully closed position. A pad 0 of rubber orthe like at the bottom of the window opening serves to prevent rain fromentering the interior of the panel A when the window is closed. It willof, course. be understood that when the -window sash is lowered, the twopulleys E E and their frame rise in the casing E and compress the springE, the pulley system serving to enable a comparatively long path oftravel of the window sash to be accompanied by a comparatively shortpath of travel of the lower pair of pulleys.

The means illustrated forblamping the window sash in position at anydesired height comprise (at each side of the window opening) a verticalrod G which is pivoted atits upper end in the upper end of the rabbet ofthe window post B and in fact constitutes one of the side walls of thegroove in which the window sash slides, as shown, clearly in Figs. 2 and,3. Each rod is U-shaped in section and embraces a strip of rubber Gwhich projects beyond the longitudinal edges of therod. The lower end ofeach rod is forked to transversely embrace the corresponding outer endof a bar H at the bottom of the window opening. Each bar H is slidablyhoused in the cross rail at the top of the panel A (Fig. 2) and isinclined at its outer end, as seen clearly in Fig. 6, so that when it isreciprocated it acts as a cam and causes the pivoted rod G to move aboutits pivot in a plane perpendicular to the face of the window sash. Anoutward movement of the bar H, as indicated by the arrow in Fig. 6,causes the lower end of the rod Gr to move in the direction of the arrowshown adjacent to it in this figure, and thereby causes the rubber stripG (Fig. 3) to press against the metal strip on the edge of the glassthereby keeping the window sash in its adjusted position as shownclearly in Fig. 3.. When the bars H H are retracted, the rods G G rockabout their pivots away from the metal strips of the window sash and thelatter then automatically closes under the influence of the springs E.

- One convenient form of mechanism for reciprocating the bars H H isshown in 'Figs. 7, 8 and 9. The inner ends of the bars work in a box Jand are specially shaped so that their slots H and their cutawayportions H H cooperate with one another to form tracks in. which twodiametrically situated pins K" K work in such a manner that when thedisk K, on which the pins K K are formed, is oscillated, the

bars H H are reciprocated. This action will be evident from inspectionof F igs. 7 and 8 and it need merely be mentioned that the dispositionof the parts in Fig. 8 as compared with the disposition in Fig. 7 iswill be readily understood by the foregoing description, but it maybeexplainedtliat.

if the window is closed and, it isjdesirefd to open it, the operatorgrips the button, D and draws the window sash down to-the desiredpositionin opp sition to the springs E on each side of the window, andthen ,ron turns the handle K in the direction that 7 causes thetransverse bars H H to rock the rods G. G toward the window sash,thereby causing the rubber strips G G! to press upon the metal strips onthe edges of the. window sash and hold the latter in posi-' tion. Inorder to close the window again it 'is merely necessary to turn backthe, handle K to its former position;

l/Vhat I claim as my invention and desire. to secure by Letters Patentof the United States is V V 1. The combinat on with a normallyspring-closed slid ng window sash and sash frame, of vertical rcdsmounted to sw ng about horizontal pivots on theframe in a directionperpendicular to the face of the sash and thereby exert pressure uponthe vertical edges thereof, transversely movable bars at the bottom ofthe window open'ng. Y

for effecting the swinging movement of the aforesaid rods, a handle, andmeans whereby manipulation of the handle eflects reciprocation of' thebars, both outward or both inward, depending upon the direction ofmanipulation of the handle. 7

2. The crmb'nation with a, vertically movable window sash and a frametherefor, of spring-actuated members housed in the vertical members ofthe frame for exerting 139 upon the two sides of the sash a closingforce sufficient to keep it normally closed, vertical rods pivoted attheir upper ends to the vertical members of the window frame inpositions such that they are capable of being rocked in planesperpendicular to the face of the sash and when rocked toward the latterexerting pressure upon the vertical edges thereof, pads carried by therods to serve as longitudinal bearing surfaces, two transversely movablebars in approximate alinement with one another, the outer ends of thebars engaging with and shaped to have a cam-like effect upon the lowerends of the pivoted rods, a disk provided with pins cooperating with theadjacent ends of the bars to effect reciprocation of the same when thedisk is oscillated, a spindle to which the disk is fixed, and a handlefor turning the spindle.

3. The combination with a sliding window sash and sash frame, ofvertical rods mounted to swing about horizontal pivots on the frame inadirection perpendicular to the face of the sash and thereby exertpressure upon the vertical edges thereof, transversely movable bars atthe bottom of the window opening for eflecting the swinglng movement ofthe aforesaid rods, a handle, and means whereby manipulation of thehandle eflects reciprocation of the bars, both outward or both inward,depending upon the direction of manipulation of the handle.

In testimony whereof I affix my signature in presence of two witnesses.
